Encountering InterfaceError (0, '') in Django Query Execution

Django users may encounter a persistent "InterfaceError (0, '')" error when attempting database operations, particularly after server restarts. This error stems from the use of global cursors.

Root Cause:

Global cursors, as their name suggests, are persistent connections to the database that remain open across multiple operations. However, MySQL, the underlying database Django often uses, has issues with global cursors and can lead to the InterfaceError when the server is under moderate load.

Resolution:

To resolve the issue, switch to creating and closing cursors within each method that requires raw query execution. This ensures that the cursors are only open during the specific operation, preventing MySQL's discomfort with global cursors.

Implementation:

Implement the following code snippet:

<code class="python">cursor = connection.cursor()
cursor.execute(query)
cursor.close()</code>
Copy after login

Replace query with the raw SQL query you wish to execute. By utilizing this approach, you can close the cursor immediately after the query is executed, eliminating the use of global cursors and resolving the InterfaceError.
